lhis invention relates to Wash-out plugs for locomotive, marine andotherobo lers, and more particularly to o 1nted plugs, and ,ll? 18 anobject oi'the inventionto provide a plug 1s protected 5 of this'typefin' which the oint iroin the excess ofboiler Water. To this end,the .joint is arranged'inside the body'of the plug. 7 i I Various" typesof Wash-out plugs have' al- 1 10 1 ready been proposed; and it haisalsobeenproposed-to connect the bolt and the body ioithe plug by a joint.

The invention-1n which a 'p'lug having a body and abolt which is movablewith respect to the body and beexchange'able, are provided, isdistinguished froinjthe existing:

I "1, A Wash-out comprising abody, bolt,*a spherical face on said bolt,anda head adapted to be inserted in said cavity, a. i" I,

threaded sleeve insert-ed in said body and spherical' face on saidfbolt,and a'threaded sleeve inserted in said head and having a sphericalcavlty fitt ng said face.

, types of plugs intha-t the joint which may bea ball-and-socketjoint,isf'arrangediwithe" I c in the body of the plugand consequentlypro-' tected' from the action of the boiler Water. 7

Another important feature of this arrange:

* ment is that theboltfdoes.not extend through the body and, sov thepacking requiredrin u v y c 1s dispensedwith. i I

In the draw ng accompanying this speci- 4 fication a plug embodyingthepresent invention is illustrateddiagrammatically: by vvay of example. i

In the drawing 1 I Y. Fig. 1 is an end elevation of the plug, Fig. 2 isan axial section. I

' Referring now tothe drawing, a is the body of the plug, bis asqua'recavity in the body, and c is a parallel threaded hole in the body"adjoining-the cavity 6; (Z is the bolt of'the plug having atitsinner'enda square head I d fittingthe cavity 2) withsome-clearance,

and a sphericalseatinterrnediate' the shank and theisquare head; :e is"cap nut fitting the thread 0 and: surrounding the shank of the bolt-With ,somef'clearance, and efis a. i

square on the outside ofthecap nut. V, 'j

I The square recess 72 prevents rotation ofthe i bolt inthebody a, thebolt 'cZ is readily'exchanged Without interfering with any parts of thebody, and the bolt is freeto assume any position With respecttothe bodya, due to the spherical connection of the parts.- Weclai1n; a V
